Deckard is peeling scales off the fish head. He grabs his wallet, produces the flake and compares it to the scales from the head. He ignores the ranting of the Chinese as he stares at the flake next to the scales.

DECKARD Fish!

CHINESE (in Chinese) What do you expect you get from fish head, stupid? (in English) Elephant shit?
